According to the elasTc rebound hypothesis, most earthquakes are produced by the rapid release of energy stored in rock that has been subjected to great forces. When the strength of the rock is exceeded, it suddenly breaks, releasing some of its stored energy as seismic waves. AFershocks and Â±oreshocks Even a great earthquake like the 1906 San Francisco earthquake usually does not release all the elasTc energy stored in the rock along a fault.

Each style offers different advantages. You can also select from a few different disconnect styles. A disconnect is the mechanism by which a drawer is released from the cabinet, desk or other housing.
